About this 1ct lab-grown oval diamond

This 1ct lab-grown oval sits in the classic one-carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a top-tier cut grade and certified by IGI LG472171953 or 472171953. Listed at 11 retailers as of October 26, 2026, with a 208% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface.
